In detail, it should be noted that the intelligent contract may include a first processing logic and a second processing logic corresponding to the real-time processing task, where the second processing logic is configured to process the working condition data according to the real-time processing operator, and the first processing logic is configured to perform a simulation operation on the processed working condition data by using data of the current block chain state database to obtain a read-write set.
Further, an embodiment of the present application further provides a data processing apparatus, where functions implemented by the data processing apparatus correspond to steps executed by the foregoing method. The data processing device may be understood as a processor of the above block chain node device 300, or may be understood as a component which is independent from the above block chain node device 300 or a processor and realizes the functions of the present application under the control of the block chain node device 300. The data processing device can comprise an intelligent contract storage module and a processing module.
The intelligent contract storage module is used for storing the intelligent contract sent by the server.
And the processing module is used for receiving a signature block chain transaction obtained by the data processing equipment performing signature processing on the block chain transaction according to the stored private key through the server, and processing the signature block chain transaction according to the intelligent contract to obtain a corresponding read-write set.
The processing module is specifically configured to decode the signature block chain transaction to obtain corresponding operating condition data, and process the operating condition data according to processing logic included in the intelligent contract to obtain a read-write set.
In the embodiment of the present application, after the intelligent contract is installed, the working condition data can be reported, and a specific flow is shown in fig. 10:
1. the device (the data processing device 100 described above) may directly construct the operating condition data to be uploaded as a block chain transaction request, sign the request using a certificate and a private key issued by an embedded block chain member service, obtain a signed block chain transaction, and then upload the signed block chain transaction to a message queue based on the MQTT protocol (the first segment is submitted to start);
the MQTT-block chain bridge service subscribes a signature block chain request uploaded by a device from an MQTT message queue;
the MQTT-block chain bridge service registers and logs in through a block chain member service to become a legal client of the block chain;
the MQTT-blockchain bridge service, as a blockchain client agent, forwards a blockchain transaction request with a working condition load signed between devices to each blockchain node (the above-mentioned blockchain node device 300) in the blockchain network, and initiates the blockchain transaction request;
5. the block chain link point decodes the received block chain transaction request into working condition data, and transmits the working condition data to a working condition real-time processing task deployed in the data real-time processing operation in a Remote Procedure Call (RPC) mode;
6. after receiving the working condition data through the remote process calling source, the working condition real-time processing task transmits the decoding to the real-time processing operator;
7. the real-time processing operator processes the working condition data and sends the processed working condition data to a remote procedure call sink in the real-time processing task;
8. remote procedure call is missed, and the processed working condition data is returned to the intelligent contract;
9. the intelligent contract utilizes the data of the current block chain state database to carry out simulation operation on the processed working condition data to obtain a corresponding read-write set, and the read-write set is signed by the private key of the block chain node and then returned to MQTT-block chain bridge service (the first section is submitted to be finished);
the MQTT-block chain bridge service collects the read-write sets simulated and signed by each node of the block chain, summarizes the read-write sets and sends the read-write sets to an MQTT message queue (the second stage of submission begins);
11. the device subscribes to a first signature read-write set transmitted by the MQTT-block chain bridge service, and submits a load signature to the first signature read-write set by using a private key of the device after decoding to obtain a signature result;
12. the device uploads the signed block chain transaction (signature result) submission to the MQTT message queue;
MQTT-blockchain bridge service subscribes to device-signed blockchain transaction commit payload;
the MQTT-block chain bridge service submits signed transactions to a block chain ordering service;
15. and the block chain sorting service sorts the block chain transaction, generates a block and distributes the block to each block chain node, and submits the block chain transaction to a local block chain account book (the second stage of submission is finished).
Wherein, message queue, MQTT-block chain bridge service, block chain member service and block chain sequencing service based on MQTT protocol are arranged on the server 200. When distributing the signature result, the server 200 performs sorting processing on the signature result through the blockchain sorting service, and distributes the sorted signature result to each blockchain link point device 300.
In summary, according to the data processing method and apparatus provided in the embodiment of the present application, a private key stored in a device itself is used to sign a block chain transaction to obtain a signature block chain transaction, and the signature block chain transaction is sent to a block chain node device, so that the block chain node device processes the signature block chain transaction according to an intelligent contract commonly recognized by multiple parties, thereby ensuring that data in the midway is not tampered, and avoiding the problems that the block chain transaction is not submitted by the device itself in the prior art, the processing logic of the block chain node is not commonly recognized by multiple parties, the data in the midway cannot be guaranteed to be tampered, and the security of data processing is low.
